Synthesis and Faraday Effect of Fe-Al Oxide Composite Ferrofluid  [PDF]
Min Dai, Shengli Pu
Advances in Materials Physics and Chemistry (AMPC) , 2015, DOI: 10.4236/ampc.2015.58034
Abstract: A kind of ferrofluid containing Fe-Al oxide composite nanometer particles was synthesized. The ferrofluid made of Fe-Al oxide composite nanometer particles which ratio was Fe:Al2O3 = 3:1 and thermally treated at 300°C showed Faraday effect approximate linearity versus the magnetic field B, and a relatively excellent Faraday effect without saturation in varying 0 - 1.5T magnetic field, which provided a method for synthesizing the ferrofluid of Faraday rotation still continuing in a relatively high magnetic field.

Abstract: A comparative study on the field attraction effects of different attractant, trap, lure and controlled-releasing amount on Monochamus alternatus showed that four test attractants had a certain trapping ability to Monochamus alternatus, among which, MA2K05 was the strongest, with a mean capture efficiency of 26.3 individuals each trap and being attractive to other species of Loleoptera and Hemiptera; MA2K13 took the second place, with 21.3 individuals each trap; while MA2K11 was the weakest, with 13.8 individuals each trap. Among the three lures tested, lures C (60 ml plastic cup with 2 of 5 cm round holes on the cover) and B (20 ml specified controlled-releasing plastic bottle) had a comparatively stronger effect, with a capture efficiency of 34.25 and 20.3 individuals each trap, respectively; while lure A (20 ml specified controlled-releasing plastic bottle, the releasing amount being smaller than that of lure B) was the weakest, with 14.7 individuals each trap. Because the attractant volume of lure C was 1.5 times larger than that of lures B and A, and the attractant for lure C was appended every 3-5 d, while that for lures B and A could be used for more than a month with once appended, lure B was the best on the whole. As for the test traps, Xuanzhou trap was superior to imitated Japanese trap, with a trapping efficiency of 36.4 and 9.7 individuals each trap, respectively. The attractiveness of attractants was not significantly enhanced when the dosage was increased from 20 ml to 80 ml, but significantly improved when it was up to 120 ml.

Abstract and Applied Analysis , 2012, DOI: 10.1155/2012/913809
Abstract: Using Mönch fixed point theorem, this paper proves the existence and controllability of mild solutions for nonlinear mixed type integrodifferential functional evolution equations with nonlocal conditions in Banach spaces, some restricted conditions on a priori estimation and measure of noncompactness estimation have been deleted, our results extend and improve many known results. As an application, we have given a controllability result of the system.

Request Strategies in Contemporary Chinese Teledramas—A Corpus-based Study
Shengli Wang
Theory and Practice in Language Studies , 2012, DOI: 10.4304/tpls.1.9.1139-1149
Abstract: This study was designed to explore the issue of request strategies in the Chinese setting by establishing a corpus of vedio clips of contemporary Chinese teledramas on the basis of an overview of previous studies on Chinese request strategies. In the present study, we chose 3970 short sequences of video clips from 35 Chinese teledramas which vividly describe the Chinese people’s life in the contemporary times. Taking the two variables of power and distance as reference points, nine situations were designed in this study. Elaborate request strategies were expected to be consecutively elicited in the nine situations of the 35 contemporary Chinese teledrama serials from the perspectives of social power and social distance in the section. It offered a new research method and idea for the future speech acts research.
An Experimental Study of Chinese English Major Students’ Listening Anxiety of Classroom Learning Activity at the University Level
Shengli Wang
Journal of Language Teaching and Research , 2010, DOI: 10.4304/jltr.1.5.562-568
Abstract: Foreign language anxiety is one of the best predictors in accounting for individual differences in language learning success in SLA, and that it is proved to be one of the most essential and influential affective factors. The present study adopts English listening tests and questionnaire to conduct a survey on English listening classroom anxiety with 125 English majors as its subjects. The results show that there exist certain negative correlations both between English listening classroom anxiety and listening achievement. This thesis investigates the influence anxiety has on listening comprehension, explores the potential sources of foreign language listening anxiety, and puts forward some coping strategies from various aspects such as learners’ psychology, teaching techniques, etc. in a hope to create a low-anxiety classroom atmosphere, and help to improve students’ listening performance and proficiency in a most favorable affective state.
Soft and Hard Interactions in proton + proton collisions at sqrt(s)=200GeV
Shengli Huang
Physics , 2004,
Abstract: We present a detailed study of particle production at mid-rapidity in proton + proton collisions at RHIC for sqrt(s)=200GeV. The transverse momentum spectra and the of inclusive hadrons and identified particles as a function of multiplicity are measured in minimum bias, "soft" and "hard" event classes. It is found that the multiplicity dependence of in soft events in proton + proton collisions does not change from RHIC to Tevetron while there is no such scaling behavior in minimum-bias and hard events. The baryon and strangeness production derived from the particle ratios of K-/pi- and Pbar/pi- are measured to be different in "soft" and "hard" events. These results are compared to model predictions and those from Au+Au collisions at RHIC.
Measurements of identified particle anisotropic flow in Cu+Au and U+U collisions by PHENIX experiment
Shengli Huang
Physics , 2012, DOI: 10.1016/j.nuclphysa.2013.02.038
Abstract: In this paper, new measurements of anisotropic flow ($v_{1}$, $v_{2}$) for identified particles such as pions and proton in Cu+Au collisions at 200 GeV and U+U collisions at 193 GeV are reported. The anisotropic flow is studied as a function of $p_{T}$ and centrality in these two collision systems. In ultra-central U+U collisions (0--2% centrality), $v_2$ of protons shows a weak $p_{T}$ dependence for $p_T<$~1.0 GeV/c. A positive $v_1$ for charged pions is observed for $p_{T} >$ 1 GeV/c with respect to the first-order event plane, the angle of which is determined by the Au-going spectators. The scaling of identified particles $v_2$ with the number of valence quarks ($n_q$) has been observed, in different centrality bins, with the transverse kinetic energy in these two collision systems.

Abstract: The Chinese government continued implementation of the strategy of “The Belt and Road”. The strategy has brought new opportunities for China and South Asia economic and trade cooperation. According to the “UN” UN-COMTRADE database, measuring the trade of China and South Asia of each index, revealed comparative advantage index, export similarity index, the specialization of the revised coefficient and coefficient of consistent indices, analysis competitive and complementary of China and south Asian countries trade. Results show that the trade structure of China and South Asia has a certain competitiveness, but also has a lot of complementarity. There are lots of varieties for trade. Chinese exports to South Asia have a wide range of categories, export manufactured goods are the main products. South Asian exports to China are the low value-added primary products and semi-finished products mainly. Under the background of the strategy of “The Belt and Road”, policy measures should be taken to promote China’s economic and trade relations with south Asian countries.

Abstract: This article collected panel data of fifteen states of Xinjiang between 2005 and 2011, and based on the method of quantile regression, made an empirical research among financial development and economic growth of Xinjiang fifteen states. The financial related rate, the efficiency of financial intermediation, the structure of financial savings and insurance depth were included in this paper. Conclusion: Comprehensive financial development level (LNFIR, LNFAE, LNFSS, LNIND) in different quantile level factor of economic growth, regional financial development level of Xinjiang restricts economic growth. Finally, this paper, according to the empirical results, puts forward the “financial development cycle theory”, and puts forward some suggestions.
